Question
The magnetic moment vectors $\mu_\text{s}$ and $\mu_\text{l}$ associated with the intrinsic spin angular momentum S and orbital angular momentum l, respectively, of an electron are predicted by quantum theory (and verified experimentally to a high accuracy) to be given by:
$\mu_\text{s}=-(\text{e}/\text{m})\text{S}.$
$\mu_\text{l}=-(\text{e}/2\text{m})\text{l}.$
Which of these relations is in accordance with the result expected classically? Outline the derivation of the classical result.

$\mu_\text{l}=-(\text{e}/2\text{m})\text{l}.$
